Situated among the inland prefectures of the northern part of the Kantō region, Tochigi is contiguous with Ibaraki, Gunma, Saitama, and Fukushima Prefectures.

The climate of Tochigi may be classified as a humid temperate zone with broad variations in temperature. Winters are arid with dry winds, while summers are humid with frequent thunderstorms.

The population of Tochigi as of November 2010 is approximately 2,005,096.

Located in the center of the prefecture is the largest open plain in the Kantō region. Shirane (2,578 m), Nantai (2,484 m) and Nasudake (1,917 m) mountain are in the northern part of the area. Kinugawa, Nakagawa, and Watarase River originate in this region, which flow across the Kanto plain before emptying into the Pacific Ocean. Tochigi is the 20th largest prefecture in Japan with a total area of 6,408 square km.

In the early 15th century, Ashikaga Gakko, Japan's oldest school of higher education, was re-established, holding over 3000 students by the 16th century. Saint Francis Xavier introduced Ashikaga to the world as the best university in Japan.

In the early 17th century, Japan was unified by the shōgunTokugawa Ieyasu. After his death, Tōshō-gū shrine was built in Nikko on what the shoguns thought of as holy ground to protect and worship Ieyasu. The establishment of the Nikkō Tōshō-gū in 1617 brought Nikkō to national attention.[citation needed] The Tokugawa Shogunate developed the Nikkō Kaidō (日光街道, part of the major road connecting Nikkō with Edo) and required lavish processions to worship Ieyasu, the founder of the Tokugawa line of shoguns.

In the late 19th century the Tokugawa Shogunate fell and the new government established the prefectures. The prefectural capital was established in the city of Tochigi after the unification of Utsunomiya Prefecture and Tochigi Prefecture in 1873.[citation needed] By 1884, however, the capital was transferred to Utsunomiya.

Located close to Tōkyō, Tochigi is home to many corporations and industrial zones, including the KiyoharaIndustrial Complex, one of the largest inland industrial complexes in the country.

Industrial manufacturing accounts for 36.6% of the prefecture's total output. Vehicle parts and accessories are the primary products, followed by vehicles, radios and televisions, pharmaceuticals, and wireless communication equipment.

The annual gross agricultural output in Tochigi is about 274 billion yen. Rice, vegetables, and livestock are produced in the region. Tochigi is also known for strawberries, Chinese chives, and Japanese pears sold throughout Japan and exported to other countries. Approximately 55% of Tochigi is covered by forests. Mushrooms, such as Shiitake mushrooms, make up half of the forest industry, with an output of approximately 5.6 billion yen.

A more recent and modern attraction is the Twin Ring Motegi Circuit race course, which hosts the only IndyCar race outside the United States. The track also hosts many other race events including Formula One and motorcycle races as well as festivals and fireworks events.

Tochigi has many traditional festivals and events such as Nikkō Tōshō-gū's 1000 Samurai Procession and Horseback Archery Festival, and the city of Tochigi's Autumn Festival where doll floats are pulled around the city once every five years.

Traversing the prefecture along the north-south axis and connecting to the rest of the country are the Tōhoku Expressway and the new and old Route 4. From east to west spans Route 50, connecting southern Tochigi with Ibaraki and Gunma Prefectures.

Also connecting Tochigi, Gunma, and Ibaraki is the Kita-Kantō Expressway, with the 18.5 km that connect the Tochigi-Tsuga Interchange and the Utsunomiya-Kaminokawa Interchange. Portions of the Kita-Kantō Expressway are still being constructed and is set to be fully completed by 2011. The highway will link the region's other main transport arteries, the Tōhoku, the Jōban and the Kan-Etsu Expressways, providing a link to the international port of Hitachinaka in Ibaraki.

The Tōhoku Shinkansen and the JR Utsunomiya Line are the main railways running north and south in Tochigi. Shinkansen runs from Tokyo Station to Oyama in south Tochigi in 43 minutes. Utsunomiya can be reached by rail in as little as 48 minutes, and many parts of Tochigi are within commuting range of central Tokyo. To the east and west, the Mito and Ryōmō Lines connect Tochigi to Ibaraki and Gunma.
